Overall Image of Service Provided

First an overall image of the service which the information management system according to the present embodiment provides will be described. FIG. 1A is a diagram illustrating an overall image of service provided by a control system according to the present embodiment. The control system includes a group 100, a data center operator 110, and a service provider 120.

The group 100 is, for example, a corporation, an organization, a home, or the like; the scale thereof is irrelevant. The group 100 has multiple devices 101 including a device A, device B, and device C, a home gateway 102, multiple battery packs 103, a distribution board 104, and a display device 105. The multiple devices 101 include those which are capable of connecting to the Internet, (e.g., a smartphone, personal computer (PC), television set, etc.), and those which are incapable of connecting to the Internet on their own (e.g., lighting, washing machine, refrigerator, etc.). There may be in the multiple devices 101 those which are incapable of connecting to the Internet on their own but can be connected to the Internet via the home gateway 102. A user 10 also uses the multiple devices 101 within the group 100.

The devices A and B are devices which are used indoors, such as a washing machine, refrigerator, vacuum cleaner, or the like, for example, and the device C is a device which is used outdoors, such as a bicycle, automobile, or the like, for example.

The multiple battery packs 103 are mounted to multiple devices 101 or the distribution board 104, thereby functioning as the power source for the multiple devices 101 or the distribution board 104.

The distribution board 104 supplies electric power supplied from a system power source to loads (multiple devices 101) provided in the building. The system power source is an electric power providing system which a power company provides. The distribution board 104 also charges the battery packs 103 that are mounted, and supplies power supplied from the battery packs 103 in time of power outage to the loads (devices 101).

The display device 105 is a device having a display function. The display device 105 is, for example, a smartphone, a personal computer, a tablet terminal, a cellular phone, a television, a home controller that controls the devices disposed within the group 100, and so forth. In other words, the display device 105 is an information terminal having a display (omitted from illustration).

The data center operator 110 includes the cloud server 111. The cloud server 111 is a virtual server which collaborates with various devices over the Internet. The cloud server 111 primarily manages massive data (big data) or the like that is difficult to handle with normal database management tools and the like. The data center operator 110 manages data, manages the cloud server 111, and serves as an operator of a data center which performs the management. The service that the data center operator 110 provides will be described in detail later.

Now, the data center operator 110 is not restricted a company which performs just management of data and operating the cloud server 111. For example, In a case where a device manufacturer which develops and manufactures one of the devices of the multiple devices 101 manages the data or manages the cloud server 111 or the like, the device manufacturer serves as the data center operator 110, as illustrated in FIG. 1B. Also, the data center operator 110 is not restricted to being a single company. For example, in a case where a device manufacturer and a management company manage data or manage the cloud server 111 either conjointly or in shared manner, as illustrated in FIG. 1C, both, or one or the other, serve as the data center operator 110.

The service provider 120 includes the server 121. The scale of the server 121 here is irrelevant, and also includes memory or the like in a PC used by an individual, for example. Further, there may be cases where the service provider 120 does not include a server 121.

Note that the home gateway 102 is not indispensable to the above-described service. For example, in a case where the cloud server 111 performs all data management, the home gateway 102 is not needed. Also, there are cases where there are no devices which cannot connect to the Internet by themselves, such as a case where all devices in the home are connected to the Internet. Note that the display device 105 may be one of the devices 101.

Next, The flow of information in the above service will be described. The device A and the device B in the group 100 each transmit log information to the cloud server 111 of the data center operator 110. The cloud server 111 collects log information from the device A and device B (arrow 131 in FIG. 1A). Here, log information is information indicating the operating state of the multiple devices 101 for example, date and time of operation, and so forth. For example, log information includes television viewing history, recorder programming information, date and time of the washing machine running, amount of laundry, date and time of the refrigerator door opening and closing, number of times of the refrigerator door opening and closing, and so forth, but is not restricted to these, and various types of information which can be acquired from the various types of devices may be included. The log information may be directly provided to the cloud server 111 from the multiple devices 101 themselves over the Internet. Alternatively, the log information may be temporarily collected from the devices 101 to the home gateway 102, and be provided from the home gateway 102 to the cloud server 111.

Also, the cloud server 111 collects log information from each of the multiple battery packs 103 (arrow 131 in FIG. 1A). Here, log information is information includes battery identifiers for identifying the battery packs and device identifiers for identifying the devices to which the battery packs are mounted. The log information may be directly provided to the cloud server 111 from the multiple battery packs 103 themselves over the Internet. Alternatively, the log information may be temporarily collected from the multiple battery packs 103 to the home gateway 102, and be provided from the home gateway 102 to the cloud server 111. Further, the log information may be output from the battery packs 103 to the devices 101 to which the battery packs 103 are mounted, and provided from the devices 101 to the cloud server 111.

Next, the cloud server 111 of the data center operator 110 provides the collected log information to the service provider 120 in certain increments. The certain increment here may be an increment in which the data center operator 110 can organize the collected information and provide to the service provider 120, or may be in increments requested by the service provider 120. Also, the log information has been described as being provided in certain increments, but the amount of information of the log information may change according to conditions, rather than being provided in certain increments. The log information is saved in the server 121 which the service provider 120 has, as necessary (arrow 132 in FIG. 1A).

The service provider 120 then organizes the log information into information suitable for the service to be provided to the user, and provides to the user. The user to which the information is to be provided may be the user 10 who uses the multiple devices 101, or may be an external user 20. An example of a way to provide information to the users 10 and 20 may be to directly provide information from the service provider 120 to the users 10 and 20 (arrows 133 and 134 in FIG. 1A). Also, an example of a way to provide information to the user 10 may be to route the information to the user 10 through the cloud server 111 of the data center operator 110 again (arrows 135 and 136 in FIG. 1A). Alternatively, the cloud server 111 of the data center operator 110 may organize the log information into information suitable for the service to be provided to the user, and provide to the service provider 120. Also, the user 10 may be different from the user 20 or may be the same.

The overall image of the service is the same in each of the embodiments described below, so the embodiments will be described using the same reference numerals.

Next, in step S27, the mounted device identifying unit 403 of the cloud server 111 identifies the devices 101 to which the first battery pack 103 a, second battery pack 103 b, and third battery pack 103 c are mounted, based on the device identifier included in the received log information, and identify the multiple devices 101 correlated with the display device 105 which has transmitted the display request. At this time, not all of the multiple devices 101 correlated with the display device 105 may necessarily have a battery pack mounted.

Next, in step S28, the display information generating unit 406 of the cloud server 111 generates display information for notification of the mounted state of the identified battery packs. The display information at this time includes information indicating the multiple devices to be displayed on the display device 105, and information relating to which of the multiple devices to be displayed on the display device 105 that the battery packs to be displayed on the display device 105 have been mounted to.

Next, in step S29, the display information transmission unit 407 of the cloud server 111 transmits the generated display information to the display device 105 which has transmitted the display request. The display information reception unit 501 of the display device 105 receive the display information transmitted from the cloud server 111.

Next, in step S30, the information display unit 502 of the display device 105 displays the received display information on the monitor 256. Thus, when accepting a request to display the mounted state of battery packs 103 corresponding to battery identifiers associated with a display device 105, to devices 101, the cloud server 111 may control the display device associated with the battery identifiers to display information indicating that the battery packs corresponding to the acquired battery identifiers are mounted to device corresponding to the acquired device identifiers. Thus, the user can confirm whether or not the battery packs are mounted to devices, and if mounted to devices, the user can confirm to which devices the battery packs are mounted.

FIG. 10 is a diagram illustrating an example of display information displayed on the monitor of the display device in the modification of the present first embodiment. For example, four battery packs are associated with the display device 105, as well as four devices being associated therewith. The four battery packs are a battery pack No. 2, a battery pack No. 5, a battery pack No. 7, and a battery pack No. 8. The four devices are an automobile, a bicycle, a vacuum cleaner, and a toilet device.

The information display unit 502 of the display device 105 displays a device image 1011 indicating the automobile, a device image 1012 indicating the bicycle, a device image 1013 indicating the vacuum cleaner, and a device image 1014 indicating the toilet device. The information display unit 502 also displays battery images 1031, 1032, 1033, and 1034, indicating the mounted states of battery packs, superimposed on the device images 1011 and 1012. The battery images 1031 and 1032 illustrated in FIG. 10 represent the battery pack No. 2 and battery pack No. 7 respectively, and the battery images 1033 and 1034 indicate that these battery packs are not mounted. Further, the information display unit 502 display battery images 1035 and 1036 at the perimeter of the device images 1013 and 1014, indicating the mounted state of battery packs. The battery images 1035 and 1036 illustrated in FIG. 10 represent the battery pack No. 5 and battery pack No. 8, respectively.

The display screen illustrated in FIG. 10 further has displayed information 1051, 1052, 1053, and 1054, for identifying battery packs corresponding to battery identifiers. Each information 1051, 1052, 1053, and 1054 is a name for identifying each of the multiple battery packs in the home, indicated by numbers such as “02” and “07”, for example. “02” represents battery pack No. 2, and “07” represents battery pack No. 7.

The control unit 231 of the cloud server 111 thus effects control so that battery images (second image) indicating the mounted state of battery packs are disposed around device images (first image) indicating devices that have been mounted with battery packs. The control unit 231 of the cloud server 111 also effects control so that the battery images (second image) indicating the mounted state of battery packs are disposed superimposed on the device images (first image) indicating devices that have been mounted with battery packs. Thus, the user can be presented with which battery packs have been mounted to which devices.

The control unit 231 of the cloud server 111 may, upon having received a request from a certain display device to display the battery pack mounted state of a certain device out of the multiple devices, acquire information relating to the number of battery packs that can be mounted to the certain device and the mounted state of the battery pack. The control unit 231 of the cloud server 111 may then, based on the acquired information, display the number of battery packs that can be mounted to the certain device in an identifiable manner, and also display a state in which a battery pack is mounted and a state in which a battery pack is not mounted, in mutually different display forms. That is to say, three battery packs can be mounted to the device corresponding to the device image 1011 in FIG. 10, so three battery images 1031, 1032, and 1033 are displayed. Further, two battery packs are mounted to the device corresponding to the device image 1011, the battery images 1031 and 1032 are displayed indicating that the battery packs are mounted, and the battery image 1033 is displayed indicating that the battery pack is not mounted. The battery images 1031 and 1032 are images representing battery packs. The battery image 1033 is displayed by dashed lines, indicating that the battery pack is not mounted.

Also displayed along with battery images indicating that battery packs are mounted, is information for identifying the battery packs that have been mounted out of the multiple battery packs in the home. For example, information for identifying battery packs is displayed above the battery images representing the battery packs in FIG. 10, such as “02” corresponding to battery pack No. 2 being displayed above the battery image 1031. This allows which battery pack in the home is mounted to which device to be easily comprehended.

Although the mounted state of battery packs corresponding to multiple devices to which battery packs can be mounted in the home is displayed in the present embodiment, the present disclosure is not restricted to this in particular; an arrangement may be made where only which devices have been mounted with battery packs associated with the display device is displayed.

Although the cloud server 111 obtains log information from the battery pack 103 after having accepted a display request from the display device 105 in the present embodiment, the present disclosure is not restricted to this in particular. An arrangement may be made where the cloud server 111 receives log information at the point of the battery pack 103 being mounted to the device 101, with the received log information being stored in the storage unit 233. The cloud server 111 may then read out the log information stored in the storage unit 233 and generate display information at the time of accepting the display request from the display device 105.

Also, upon the user making a request to display the mounted state of battery packs 103 in the present embodiment, the display request is transmitted to the cloud server 111, log information is read out from the storage unit 233 of the cloud server 111, and display information is generated, but this is not restrictive.

An arrangement may be made where the display request is transmitted to a battery pack 103 associated with the display device, the display device 105 acquires log information from the storage unit 217 of the battery pack 103, and acquires display information. The display information here is not generated at the cloud server 111 but within the display device 105. That is to say, the display device 105 has a display information generating unit having functions the same as the display information generating unit 406.

Although multiple devices associated with the display device beforehand are displayed in the present embodiment, with the state of mounting the battery packs to the devices also being displayed, the present disclosure is not restricted to this in particular. The display request transmitted from the display device to the cloud server may include information specifying a device regarding which the mounted state of a battery pack is to be displayed, and the specified device may be displayed along with display of the mounted state of the battery pack to the specified device.

Further, although multiple devices associated with a display device beforehand are displayed in the present embodiment, the present disclosure is not restricted to this in particular; the user household ID and multiple devices may be associated beforehand, with all devices associated with the user household ID being displayed. In this case, the cloud server 111 may acquire information relating to the number of battery packs which can be mounted to each of all devices which a certain household has, and the mounted state of the battery packs, when accepting a request from a certain display device to display the mounted state of battery packs of multiple devices which the certain household has. The cloud server 111 may then display the number of battery packs which can be mounted to each of all devices which the certain household has, in an identifiable manner, and also display a state in which a battery pack is mounted and a state in which a battery pack is not mounted, in mutually different display forms.

The storage unit 233 of the cloud server 111 may also store a table correlating beforehand battery packs, at least one device to which a battery pack is mounted, and a user using the battery pack. Upon a battery pack being mounted to one device of multiple devices, the control unit 231 of the cloud server 111 may reference the table, and determine whether or not the device to which the battery pack has been mounted is a device correlated with the user of the battery pack beforehand. Further, in a case where the device to which the battery pack has been mounted is not a device correlated with the user of the battery pack beforehand, the control unit 231 of the cloud server 111 may display on the display device, associated with the user of the battery pack, information indicating that the battery pack is not mounted to a device correlated with the battery pack.

Accordingly, in a case where the battery pack is mounted to a device other than a device registered beforehand, the user of the battery pack is notified that the battery pack is not mounted to a device registered beforehand, so the user who usually uses the battery pack can know that some other user has used the battery pack.

The battery pack 103 may also include a Global Positioning System (GPS) function (hereinafter simply “GPS”), and in a case where the battery pack is mounted to a device, current position information may be acquired from the GPS and the acquired current position information transmitted to the cloud server 111 included in the log information. The cloud server 111 may control a display device 105 associated with a battery pack to display the current position information of the battery pack as current position information of the device to which the battery pack has been mounted. In this case, the current position of the battery pack is notified to the user at the time of a stolen battery pack being mounted to a device by a person who has stolen the battery pack, so the user of the battery pack can tell the current position of the stolen battery pack.

The battery pack 103 may include a GPS, and may acquire current position information from the GPS at a predetermined timing, and transmit the acquired current position information to the cloud server 111. The cloud server 111 may control the display device 105 associated with the battery pack to display the current position information of the battery pack. The cloud server 111 may control a display device 105 associated with the battery pack to display the current position information of the battery pack as current position information of the device to which the battery pack has been mounted.

In this case, the current position of the battery pack is notified to the user as current position information in a case where a device to this the battery pack has been mounted is stolen, so the user of the battery pack can tell the current position of the stolen device.

Also, although the identifier acquisition unit 302 of the battery pack 103 acquires the device identifier for identifying the device 101 from the device 101 to which the battery pack 103 is mounted in the present embodiment, the present disclosure is not restricted to this in particular. Upon detecting having been mounted to a device 101 by the mounted state detection unit 301, the identifier acquisition unit 302 may send a predetermined current to the device 101 and measure the resistance value, thereby identifying the device 101. In this case, the identifier acquisition unit 302 may store resistance values and types of the devices 101 beforehand, and identify the type of the device 101 based on the measured resistance value.

The multiple devices may be classified into three types of devices with a large load, devices with a medium load, and devices with a small load, according to the magnitude of the load. In this case, the identifier acquisition unit 302 of the battery pack 103 may identify whether which of a devices with a large load, device with a medium load, or device with a small load, the device to which it has been mounted is, in accordance with the measured resistance value.

FIG. 12 is a diagram illustrating an example of display information displayed on the monitor of the display device in the present second embodiment. The display screen displayed in the present second embodiment as illustrated in FIG. 12 is almost the same as the display screen according to the first modification illustrated in FIG. 10. Note however, that the display screen illustrated in FIG. 12 displays the battery images 1031, 1032, 1035, and 1036, indicating that the battery packs have been mounted, and also state of charge images 1041, 1042, 1043, and 1044, indicating the states of charge of the battery packs. The display information generating unit 406 of the cloud server 111 generates the display information including the states of charge of the battery packs. The states of charge are represented by bar graphs corresponding to the remaining charge in the batteries, as illustrated in FIG. 12.

The display screen illustrated in FIG. 12 further has displayed the information 1051, 1052, 1053, and 1054, for identifying battery packs corresponding to battery identifiers. Each information 1051, 1052, 1053, and 1054 is a name for identifying each of the multiple battery packs in the home, indicated by numbers such as “02” and “07”, for example. “02” represents battery pack No. 2, and “07” represents battery pack No. 7.

The cloud server 111 thus acquires the battery identifiers of all battery packs mounted to a certain device, and the remaining charge of the battery which each battery pack has, when accepting a request from the certain device to display the mounting state of the battery packs of the certain device out of the multiple devices. The cloud server 111 then effects control so as to display information for identifying the battery packs corresponding to the acquired battery identifiers, and the remaining charge of the battery packs corresponding to the acquired battery identifiers.

The monitor 256 is configured as a touch panel, with battery images 1031, 1032, 1035, and 1036, representing the battery packs, being selectably displayed.

The input accepting unit 503 accepts input of the battery images 1031, 1032, 1035, and 1036, from the user. The display request transmission unit 504 transmit to the cloud server 111 a display request to display information relating to the battery pack corresponding to the battery image which the user has selected. The display information generating unit 406 generate display information including information relating to the battery pack, in response to the display request from the display device 105.

FIG. 13 is a diagram illustrating an example of display information including information relating to the battery pack selected by the user, according to the present second embodiment. In a case where the battery image 1031 illustrated in FIG. 12 is selected, the display information illustrated in FIG. 13 is displayed on the monitor 256 of the display device 105.

As illustrated in FIG. 13, the display information includes information 2011 for identifying the battery pack, information 2012 relating to the usage period of the battery pack, information 2013 relating to the life expectancy of the battery pack, information 2014 relating to whether or not there is abnormality or deterioration of the battery pack, information 2015 relating to usage history of the battery pack, and information 2016 relating to the state of charge of the battery pack.

The information 2011 represents which battery pack of the multiple battery packs in the home the information relates to. In FIG. 13, “BATTERY NO. 2” is displayed for the information 2011. The information 2012 represents the usage period of the battery pack. In FIG. 13, “1 YEAR 6 MONTHS” is displayed for the information 2012. The information 2013 represents the life expectance of the battery pack. In FIG. 13, “REMAINING LIFE EXPECTANCY 1 YEAR” is displayed for the information 2013.

The information 2014 represents whether or not the battery pack is in an abnormal state or a deteriorated state. The battery pack is in neither an abnormal state nor a deteriorated state in FIG. 13, so “ABNORMALITY/DETERIORATION: NONE” is displayed as the information 2014. In a case where the battery pack is in an abnormal state or a deteriorated state, “ABNORMALITY/DETERIORATION: PRESENT” is displayed as the information 2014. Information regarding whether or not the battery pack is in an abnormal state or a deteriorated state is included in the log information.

The information 2015 represents the usage history of the battery pack, and indicates how many times the battery pack has been used by each device. In FIG. 13, “HYBRID CAR: 34 TIMES”, “BICYCLE: 12 TIMES”, and “CLEANER: 1 TIME” are displayed as the information 2015. Display may also be made regarding how many hours the battery pack has been used by each device, not just the number of times of use of the battery pack.

Information 2016 represents the state of charge of the battery pack. In FIG. 13, a bar graph indicates the remaining charge in the battery as the information 2016.

In this way, information relating to the battery pack is displayed, such as the information 2012 relating to the usage period of the battery pack, information 2013 relating to the life expectancy of the battery pack, information 2014 relating to whether or not there is abnormality or deterioration of the battery pack, information 2015 relating to usage history of the battery pack, and information 2016 relating to the state of charge of the battery pack. Accordingly, the user can easily confirm the current state of the battery pack. Note that in the second embodiment, the cloud server 111 may effect control so as to display advertisement information, to prompt the user to purchase a replacement battery pack.

FIG. 14 is a diagram illustrating an example of display information including advertisement information to prompt the user to purchase a replacement battery pack, according to the present second embodiment. In a case where the battery image 1031 illustrated in FIG. 12 has been selected, the display information illustrated in FIG. 14 is displayed on the monitor 256 of the display device 105.

The display screen displayed in FIG. 14 is almost the same as the content of the display screen illustrated in FIG. 13. Note however, that the display screen illustrated in FIG. 14 includes advertisement information 2017 to prompt the user to purchase a replacement battery pack. In a case where the life expectancy is within one year, for example, the display information generating unit 406 of the cloud server 111 generates display information including the advertisement information 2017. In this case, the storage unit 233 of the cloud server 111 stores a Uniform Resource Locator (URL), indicating a Web site of a vendor vending battery packs, beforehand.

The advertisement information 2017 includes hypertext for displaying the Web site of the vendor vending battery packs, and is displayed superimposed on information relating to the battery pack. Upon the finger 11 of the user coming into contact with the advertisement information 2017 in FIG. 14, the Web site of the vendor vending battery packs is displayed.

Note that the display device 105 may transmit position information acquired by GPS to the cloud server 111, and the cloud server 111 may search for a vendor nearby the display device 105 based on the received position information, and effect control so as to display a vendor that has been found as the advertisement information 2017.

Thus, advertisement information 2017 to prompt the user to purchase a replacement battery pack is displayed in accordance with the life expectancy of the battery pack, so the user can purchase a replacement battery pack before the battery pack becomes unusable.

Also, the information relating to the battery pack in the present second embodiment may include devices which can operate in a case where the current battery pack is mounted. The internal resistance of batteries incases by repeated charging and discharging. In a case where a battery of which the internal resistance has increased is used in a device requiring a larger current, such as an automobile or the like, the voltage of the battery drops. If the voltage of the battery falls to or below a cutoff voltage of the device, the device stops operating. Accordingly, a battery of which the internal resistance has increased due to deterioration may not be usable with a large current load device. Accordingly, the cloud server 111 effects control so as to display information indicating devices which can operate if the current battery pack is mounted.

FIG. 15 is a diagram illustrating an example of display information including information of devices which can be operated in a case of mounting the current battery pack, according to the present second embodiment. The content of the display information illustrated in FIG. 15 is almost the same as the content of the display information illustrated in FIG. 13. Note however, that the display screen illustrated in FIG. 15 includes information 2121 indicating devices which can operate in a case of the current battery pack being mounted. The storage unit 233 of the cloud server 111 stores beforehand a table correlating devices and the number of times of charging/discharging which will render the battery pack unusable in the device, for each battery pack. The display information generating unit 406 of the cloud server 111 identifies devices which can be operated in a case of mounting the current battery pack, based on the number of times of charging/discharging acquired from the battery pack, and generates display information including the information 2121 indicating the identified devices.

Thus, devices which can operate in a case of mounting the current battery pack are displayed, so the user can identify which devices the battery pack can be mounted to. Also, the cloud server 111 may effect control so as to display information indicating devices which can operate if the current battery pack is mounted, and information indicating devices which will not operate if the current battery pack is mounted.

FIG. 16 is a diagram illustrating an example of display information including information of devices which can be operated in a case of mounting the current battery pack, and information indicating devices which will not operate if the current battery pack is mounted, according to the present second embodiment. The content of the display information illustrated in FIG. 16 is almost the same as the content of the display information illustrated in FIG. 13. Note however, that the display screen illustrated in FIG. 16 includes information 2122 indicating devices which can operate in a case of the current battery pack being mounted and devices which cannot be operated if the current battery pack is mounted. The storage unit 233 of the cloud server 111 stores beforehand a table correlating devices and the number of times of charging/discharging which will render the battery pack unusable in the device, for each battery pack. The display information generating unit 406 of the cloud server 111 identifies devices which can be operated in a case of mounting the current battery pack, based on the number of times of charging/discharging acquired from the battery pack, and generates display information including the information 2122 indicating devices which can operate in a case of the current battery pack being mounted and devices which cannot be operated if the current battery pack is mounted.

The devices which can operate in a case of the current battery pack being mounted and the devices which cannot be operated if the current battery pack is mounted are displayed in different forms from each other, as illustrated in FIG. 16. Devices which can operate in a case of the current battery pack being mounted are displayed with an image representing that device. Devices which cannot be operated if the current battery pack is mounted are displayed with a mark indicating unusable superimposed over an image representing that device.

Thus, devices which can operate in a case of mounting the current battery pack and devices which cannot be operated if the current battery pack is mounted are displayed, so the user can easily identify which devices cannot be operated if the current battery pack is mounted, and thus can mount appropriate battery packs to each device. The cloud server 111 may also effect control so as to display an operating button to control operation of the battery pack.

FIG. 17 is a diagram illustrating an example of display information including an operating button for controlling a battery pack selected by the user, according to the present second embodiment. In a case where the battery image 1031 illustrated in FIG. 12 is selected, the display information illustrated in FIG. 17 is displayed on the monitor 256 of the display device 105. As illustrated in FIG. 17, the display information includes information 2011 for identifying the battery pack, information 2012 relating to the usage period of the battery pack, information 2013 relating to the life expectancy of the battery pack, information 2014 relating to whether or not there is abnormality or deterioration of the battery pack, and an operating button 2131 to control operations of the battery pack.

The operating button 2131 is an operating button for setting the battery pack regarding whether or not to operate in an energy conservation mode. In a case of being set to the energy conservation mode, the output power of the battery pack is suppressed, and accordingly can be used for long periods of time. When the finger of the user touches the operating button 2131, the display switches between “ON” where the energy conservation mode is set, and “OFF” where the energy conservation mode is not set. Upon the operating mode (e.g., energy conservation mode) of the battery being changed by operating the operating button 2131, the communication unit 232 of the cloud server 111 transmits control information for changing the operating mode to the battery pack. Upon receiving the control information from the cloud server 111, the battery pack changes the operating mode according to the received control information. Thus, battery packs mounted to devices can be remotely controlled.

Note that the cloud server 111 may store user individual IDs for identifying users, battery packs, and battery pack operation content, in a correlated manner beforehand. In this case, identifying a battery pack and user at the time of the battery pack being mounted enables battery packs to be made to operate according to control corresponding to the identified user. The method for identifying the user will be described later.

Description has been made so far regarding a case where battery packs are mounted to devices, but the same processing is performed in cases where battery packs are mounted to a distribution board as well.

FIG. 18 is a diagram illustrating an example of display information displayed on the monitor of the display device in a case where a battery pack has been mounted to a distribution board, according to the present second embodiment. When a battery pack 103 is mounted to the distribution board 104, the display information illustrated in FIG. 18 is displayed on the monitor 256 of the display device 105. The display information illustrated in FIG. 18 may be displayed not only when a battery pack 103 is mounted to the distribution board 104, but also in a case where instructions for displaying the state of the distribution board 104 have been accepted by the input unit 257.

Displayed in the display screen illustrated in FIG. 18 are a distribution board image 2111 representing the distribution board, battery images 2021, 2022, and 2023 indicating that battery packs are mounted, and state-of-charge images 2031, 2032, and 2033 indicating the state of charge of the battery packs. The display information generating unit 406 of the cloud server 111 generates display information including the state of charge of the battery packs. The states of charge are represented by bar graphs corresponding to the remaining charge in the batteries, as illustrated in FIG. 18.

The display screen illustrated in FIG. 18 further displays information 2051, 2052, and 2053 for identifying battery packs corresponding to battery identifiers. Each information 2051, 2052, and 2053 is a name for identifying individual battery packs in the home, represented as numbers such as “01” and “03”.

The monitor 256 is configured as a touch panel, with battery images 2021, 21022, and 2023, representing the battery packs, being selectably displayed. When the finger 11 of the user touches one of the battery images 2021, 21022, and 2023, information relating to the battery pack corresponding to the touched battery image is displayed. In a case where the user selects a desired battery image, the display information illustrated in FIGS. 13 through 17 is displayed.

FIG. 19 is a diagram illustrating another example of display information displayed on the monitor of the display device in a case where a battery pack has been mounted to a distribution board, according to the present second embodiment. For example, the distribution board is provided with multiple charging spaces to mount battery packs. The distribution board not only functions as a back-up power source in a case of a power outage, but also serves as a charger to charge the battery packs with electric power. Accordingly, notifying how many battery packs can currently be mounted to the distribution board will further improve ease of use.

The display screen illustrated in FIG. 19 indicates that one of the three charging spaces provided to the distribution board 104 is empty. An image 2024 indicating a charging space where no battery pack is mounted is displayed.

Note that in the present second embodiment, the cloud server 111 may effect control so as to display battery packs currently not mounted to devices, or may effect control so as to display information relating to battery packs currently not mounted to devices.

Although multiple devices associated with the display device beforehand are displayed in the present second embodiment, and the mounted state of the battery packs to multiple devices displayed, the present disclosure is not restricted to this in particular. Information specifying devices for display of the mounted state of battery packs may be included in the display request transmitted from the display device to the cloud server, and the mounted state of battery packs as to the specified devices may be displayed along with display of the specified devices.

Also, although multiple devices associated with the display device beforehand are displayed in the present second embodiment, the present disclosure is not restricted to this in particular; user household IDs and multiple devices may be associated, with all devices associated with a user household ID being displayed. In this case, at the time of accepting, from a certain display device, a request to display the mounted state of the battery packs of the multiple devices which a certain household has, the cloud server 111 may acquire the battery identifiers of all battery packs mounted to each of all the devices which the certain household has, and the remaining charge of the batteries which each of the battery packs has. The cloud server 111 may then display the information for identifying the battery packs corresponding to the acquired battery identifiers and the remaining charge of the battery packs corresponding to the acquired battery identifiers together.

Also in the present second embodiment, upon the user making a request to display the mounted state of battery packs 103, a display request is transmitted to the cloud server 111, log information is read out from the storage unit 233 of the cloud server 111, and display information is generated, but this is not restrictive.

An arrangement may be made where the display request is transmitted to the battery pack 103 associated with the display device, with the display device 105 acquiring log information from the storage unit 217 of the battery pack 103 and acquiring display information. At this time, the display information is not generated at the cloud server 111, but within the display device 105. That is to say, the display device 105 has a display information generating unit having the same functions as the display information generating unit 406.

Also, although the life expectancy of the battery is estimated in the battery pack 103, the present disclosure is not restricted to this in particular; the cloud server 111 may acquire the charging/discharging cycle from the battery pack 103 and estimate the life expectancy using the acquired charging/discharging cycle. Also, although the usage period of the battery pack 103 is detected at the battery pack 103, the present disclosure is not restricted to this in particular; the cloud server 111 may acquire the date of starting usage from the battery pack 103 and calculate the usage period from the acquired date of starting usage.

Third Embodiment

In a third embodiment, a user using a battery pack is identified. FIG. 20 is a diagram illustrating a schematic configuration of an information providing system according to a third embodiment of the present disclosure. Upon the user 10 mounting a battery pack 103 to a device 101, the battery pack 103 performs communication with the display device 105 which the user 10 has, and acquires a user individual ID for identifying the user 10 from the display device 105. The battery pack 103 then transmits log information including the user individual ID to the cloud server 111 (or server 121) situated on the network. Note that the same processing is performed in a case where a battery pack 103 is mounted to the distribution board 104, as with a case of a battery pack 103 being mounted to a device 101. The same processing may also be performed in a case where a battery pack 103 is detached from the distribution board 104, as with a case of a battery pack 103 being detached from a device 101.

Communication between the battery pack 103 and the display device 105 is performed by wireless communication such as, for example, Bluetooth (a registered trademark) or the like. The battery pack 103 and display device 105 are paired beforehand, and accordingly are connected by coming within a communicable distance of each other.

Note that the battery pack 103 and display device 105 may each also be provided with GPS, with the battery pack 103 connecting with the display device 105 closest in proximity. Accordingly, in a case where there are multiple display devices in a communicable distance with the battery pack 103, the display device which the user that has mounted the battery pack 103 to the device 101 can be identified.

When a battery pack 103 is mounted to one of multiple devices 101, the cloud server 111 (or server 121) acquires log information including a battery identifier for identifying the battery pack 103, a device identifier for identifying the device to which the battery pack 103 has been mounted, and the user individual ID. The cloud server 111 (or server 121) controls the display device 105 associated with the battery identifier, so as to display information indicating that the user corresponding to the acquired user individual ID has mounted the battery pack corresponding to the acquired battery identifier to the device corresponding to the acquired device identifier.

The display device 105 displays information indicating that the user corresponding to the acquired user individual ID has mounted the battery pack corresponding to the acquired battery identifier to the device corresponding to the acquired device identifier.

The cloud server 111 (or server 121) stores each of the battery identifier, the device identifier, and the user individual ID, acquired from the battery pack 103, as usage history in a correlated manner. In a case where the battery pack 103 is mounted to one of the multiple devices 101, the cloud server 111 (or server 121) compares the user individual ID included in the log information acquired from the battery pack 103, with a user individual ID stored as usage history correlated with the same battery identifier as the battery identifier included in log information acquired from the battery pack 103 at the same point-in-time as the point-in-time of having acquired the log information but on a different day from the day on which the log information was acquired. In a case where the user individual IDs differ, the cloud server 111 (or server 121) controls the display device 105 corresponding to the user individual ID stored as usage history to display that the battery pack corresponding to the battery identifier has been mounted to the device corresponding to the device identifier by the user corresponding to the user individual ID.

Note that the following control may be performed in a case where a battery pack 103 mounted to one of the multiple devices 101 is detached.

Specifically, in a case where the battery pack 103 is detached from, the user individual ID of the user who has performed the detaching is compared with a user individual ID stored as usage history correlated with the same battery identifier as the battery identifier included in log information acquired from the battery pack 103 at the same point-in-time as the point-in-time of the detaching having been performed but on a different day from the day on which the detaching was performed. In a case where the user individual IDs differ, the cloud server 111 (or server 121) controls the display device 105 corresponding to the user individual ID stored as usage history to display that the battery pack corresponding to the battery identifier has been detached from the device corresponding to the device identifier by the user corresponding to the user individual ID.

Also, in a case where a user mainly using a battery pack 103 is set out of multiple users using the battery pack 103 as a main user, and a user other than the main user mounts the battery pack 103 to a device 101, control may be effected to display information to this effect on the display device 105 of the main user. A specific example of control is as follows. The cloud server 111 (or server 121) stores the user individual ID of the main user as a main user ID. Now, in a case where the battery pack 103 is mounted, the cloud server 111 (or server 121) compares the user individual ID of the user who has performed this with the user individual ID of the main user, stored in the cloud server 111 (or server 121). In a case where the user individual IDs differ, the cloud server 111 (or server 121) controls the display device 105 corresponding to the user individual ID of the main user to display that the battery pack corresponding to the battery identifier has been mounted to the device corresponding to the device identifier by the user corresponding to the user individual ID.

Also, in a case where a user other than the main user detaches the battery pack 103 from a device 101, control may be effected to display information to this effect on the display device 105 of the main user. A specific example of control is as follows. The cloud server 111 (or server 121) stores the user individual ID of the main user as a main user ID. Now, in a case where the battery pack 103 is detached, the cloud server 111 (or server 121) compares the user individual ID of the user who has performed this with the user individual ID of the main user stored in the cloud server 111 (or server 121). In a case where the user individual IDs differ, the cloud server 111 (or server 121) controls the display device 105 corresponding to the user individual ID of the main user to display that the battery pack corresponding to the battery identifier has been detached from the device corresponding to the device identifier by the user corresponding to the user individual ID.

FIG. 21 is a functional block diagram illustrating the configuration of a battery pack, display device, and cloud server according to the third embodiment of the present disclosure. Note that the hardware configuration of the information providing system according to the third embodiment is the same as the hardware configuration of the information providing system of the first embodiment illustrated in FIG. 3, so description will be omitted. Configurations in FIG. 21 which are the same as the battery pack, display device, and cloud server according to the modification of the first embodiment illustrated in FIG. 4 are denoted with the same reference numerals, and description thereof will be omitted.

The battery pack 103 includes the mounted state detection unit 301, identifier acquisition unit 302, log information transmission unit 303, and also a pairing information transmission unit 308 and a user individual ID reception unit 309. Note that the communication unit 216 illustrated in FIG. 3 includes the pairing information transmission unit 308 and the user individual ID reception unit 309.

Upon the mounted state detection unit 301 detecting that the battery pack 103 has been mounted to the device 101, the pairing information transmission unit 308 transmits pairing information to communicably communicate with a particular display device 105. Note that the pairing information is information generated in paring processing for the devices to authenticate each other. The battery pack 103 and the display device 105 stored the same pairing information.

The user individual ID reception unit 309 receives the user individual ID transmitted from the display device 105. The user individual ID is an identifier for identifying the user.

The log information transmission unit 303 transmits log information including the device identifier and battery identifier acquired by the identifier acquisition unit 302 and the user individual ID acquired by the user individual ID reception unit 309, to the cloud server 111.

The display device 105 includes the display information reception unit 501, information display unit 502, and also a pairing information reception unit 505 and a user individual ID transmission unit 506.

The pairing information reception unit 505 receives the paring information transmitted by the battery pack 103. In a case where the pairing information received by the pairing information reception unit 505 matches the pairing information stored beforehand, the user individual ID transmission unit 506 transmits the user individual ID to the battery pack 103. The user individual ID is stored in the memory 253 beforehand. Note that an identifier identifying the display device may be used instead of the user individual ID.

The cloud server 111 includes the log information reception unit 401, battery pack management database 402, mounted device identifying unit 403, mounted battery identifying unit 404, object display device selecting unit 405, display information generating unit 406, and display information transmission unit 407.

The battery pack management database 402 stores the device identifier, battery identifier, user individual ID, and date-and-time information, included in the log information received by the log information reception unit 401, as usage history for each user household (group).

FIG. 22 is a diagram illustrating an example of data stored in a battery pack management database according to the present third embodiment. As illustrated in FIG. 22, the battery pack management database 402 stores a user individual ID (user individual identifier), battery pack ID (battery identifier), device ID (device identifier), mounted state, and date-and-time information, correlated with a user household ID (user household identifier). For example, it can be understood that in a household corresponding to user household ID “0XX168”, a battery pack corresponding to battery pack ID “1” has been mounted to a device corresponding to device ID “XX01”, at 58 minutes past 10 o'clock on Dec. 17, 2013, by a user corresponding to user individual ID “A”. Note that the user household ID (user household identifier) may be included in the received log information. The storage unit 233 may also store beforehand a table in which are correlated the battery pack ID (battery identifier) or device ID (device identifier) and the user household ID (user household identifier). The log information reception unit 401 may acquire the user household ID corresponding to the battery pack ID or device ID included in the received log information from the table, and store this in the battery pack management database 402.

Upon a battery pack being mounted to one of the multiple devices, the object display device selecting unit 405 identifies the user individual ID associated with the battery pack that has been mounted at generally the same point-in-time of a day different from the day where the battery pack was mounted, based on the usage history. Note that generally the same point-in-time may mean the same point-in-time, or may mean a point-in-time within around one hour before or after the same point-in-time. The object display device selecting unit 405 compares the acquired user individual ID with the identified user identifier. In a case where the acquired user individual ID and the identified user individual ID are different, the object display device selecting unit 405 selects a display device associated with the identified user individual ID. Note that the storage unit 233 stores a table correlating user individual IDs and display devices 105 beforehand. The object display device selecting unit 405 acquires a display device 105 corresponding to the identified user individual ID from the table.

On the other hand, in a case where the acquired user identifier and the identified user identifier are the same, the object display device selecting unit 405 selects a display device associated with the battery pack ID. Note that the storage unit 233 stores a table correlating battery pack IDs and display devices 105 beforehand. The object display device selecting unit 405 acquires a display device 105 corresponding to the battery pack ID included in the received log information from the table.

The display information generating unit 406 generates display information to be displayed on the display device 105, indicating that a battery pack corresponding to the acquired battery identifier has been mounted to a device corresponding to the acquired device identifier by a user corresponding to the acquired user individual ID.

FIG. 23 is a diagram illustrating an example of display information displayed on a monitor of the display device in the present third embodiment. The mounted device identifying unit 403 identifies that the device 101 to which the battery pack 103 has been mounted is an automobile, based on the device identifier included in the log information. The mounted battery identifying unit 404 also identifies that the battery pack 103 mounted to the device 101 is battery pack No. 7, based on the battery identifier included in the log information.

When the battery pack is mounted to one of the multiple devices, the object display device selecting unit 405 also identifies the user individual ID associated with the battery pack mounted at generally the same point-in-time of a day different to the day that the battery pack was mounted, based on the usage history. Here the user who has mounted the battery pack (battery pack No. 7) to the device (automobile) is Older Brother, and the user how has mounted the battery pack (battery pack No. 7) to a device at the same point-in-time the day before, which is a day different from the day where the battery pack was mounted, is Father. In this case, the object display device selecting unit 405 select the display device associated with the identified user individual ID, because the acquired user individual ID (user individual ID of Older Brother) and the identified user individual ID (user individual ID of Father) are different. That is to say, the object display device selecting unit 405 selects the display device that Father has.

The display information generating unit 406 then generates display information saying “OLDER BROTHER HAS MOUNTED BATTERY PACK NO. 07 TO AUTOMOBILE!”. The storage unit 233 at this time may store a name or nickname or the like to be displayed on the display device 105 correlated with the user individual ID beforehand, and the display information generating unit 406 may read the name or nickname corresponding to the user individual ID from the storage unit 233 and include in the display information.

The information display unit 502 of the display device 105 displays the display information 602 “OLDER BROTHER HAS MOUNTED BATTERY PACK NO. 07 TO AUTOMOBILE!” on the monitor 256.

Note that in the present third embodiment, the control unit 231 of the cloud server 111 may identify the user of the battery pack 103 and identify a timing at which to charge the battery pack 103, based on the usage history, and control the display device 105 associated with the identified user to display the timing at which to charge the battery pack 103.

That is to say, the control unit 231 of the cloud server 111 identifies the user using the battery pack. The control unit 231 then identifies a scheduled point-in-time at which the battery pack is to be mounted to a device after the current point-in-time, based on the point-in-time at which the battery pack was mounted to the device the previous day or earlier, for example, identifies a charging completion time for charging of the battery pack to be completed based on the current remaining charge in the battery pack, and decides a point-in-time obtained by subtracting the charging completion time from the identified scheduled point-in-time as the timing at which the battery pack should be charged. The control unit 231 of the cloud server 111 controls the display device associated with the identified user to display the timing at which to charge the battery pack. Accordingly, a user who routinely uses the battery pack can be notified regarding when the battery pack should be charged.
